HTTP caching

The goal of this project is to make a RFC 7234 compliant shared caching server in Go. Tho the main goal is to have a out-of-the-box working caching server it is also important that the functionality is exported so it can be used as library in bigger projects.

Features

• Fully RFC7234 compliant (excluding optional features)
• Flexible configuration
• Multi layer system
• Customizable logging

Usage

TODO make command line usage section for the standalone cache server

Examples

For library examples please go the the godoc page

Validation

To validate the cache a testing harness like https://github.com/http-tests/cache-tests can be used.

TODO

• Adding tests, both unit and integration
• Store partial responses
• Combining Partial Content
• Calculating Heuristic Freshness based on past behavior
• Add informational headers about cache hit's ect.
• Add websocket support
• Add HTTP/2 push support
• Add optional RFC7239 support
• http cache-aware server-push link
• Add Cache-Control extensions (Or at least make a callback so someone can from outside the package)
  • RFC5861 - HTTP Cache-Control Extensions for Stale Content
  • RFC8246 - HTTP Immutable Responses
• Add metrics (prometheus)
• Add user triggered cache invalidation
• Add advanced cache replacement policies to inmemory layer
• Add disk storage layer
• Add redis storage layer
• Add s3 storage layer
